DRIVING-CAP Fon ro's'rs.

Specification of Letters Patent.

Patented. June 6, 1911.

Application led April 13, 1911. Serial No. 620,896.

To all whom it may concern:

.Be it known that I, MARION RoovAAR'r, a

citizen of the United States, residing at Ankeny, in the county of Polk and State of Iowa, have invented a new and Improved DrivmgCap for Posts, of which the following'is a specification.

This invention has for its object to provide a simple and inexpensive means in the nature of a cap for being applied to the top of wooden posts to prevent them from split ting or other injury .when struck by the driving sledge and in its generic nature the said invention comprises a cap ,portion and means for holding the same on the tops of different sizes of posts, and in which the said means automatically adjust themselves for sustaining the cap portion in the desired positions on the said different sizes of posts.

In its more subordinate features my in venton consists in the details of construction and novel combination of parts, all of which will be hereinafter fully described, specifically pointed out in the appended c aims and i lustrated in the accompanying drawings, in which Figure 1,'fis a perspective lview of the upper end of a post with my improvements attached thereto, the post being of considerably less diameter' than the cap device. Fig. 2,*is a side eleva-tion of the same and shows l.it applied to a wider post. Fig. 3, is a horizontal section on the line 33 on Fig.

2. Fig. 4, is a` similar view on the line 4f-4 on Fig. 2.

In the practical arrangement my invention comprises a band or ring 1, of a diameter sulllciently large to fit over diferent sizes of posts, and the said ring at diamet rically opposite sides has pairs of lugs l0-10 having n ertures to receive the bolts has Der arms 4--4 whose lower or pendent 64-60 being such that the said l, lates 6--60 end-the levers 5-5 are held clamped against the upper end of the post, as is clearly shown in Figs. 1 and 2. It will be observed, by

referring to Fig. 1, that the lower ends ofthe arms 4 project below the ring 1 and by reason thereof and the curvature of the members 44, when the post is of less diameter than the cap ring 1, the knuckle or joint of the levers 5 and the arms 4, is drawn in under the cap ring to bring the upper clamping plates 6, as also the lower plates against the post, it being also clear that when fitted on thicker posts t-he 'levers 5*,'5 and plates G-G0 automatically adjust themselves to the size of the said posts.

By reason of constructing and arranging the several parts, as stated, it is obvious the cap ring or band can be readily held in position over the upper ends of different sizes of posts without rearranging or adjusting the parts Since the levers with the spring connections can be easily slipped over the upper ends of the said different sizes of posts, the springs and levers and the clamping members (5*60 automatically seating on and clamping the said parts. y 2 designates a striker plate which, when small sizes of posts are to be' driven, may be heavy tin, it being understood that when it is to be used for very large posts, it may be of steel or other metal. Plate 2, is eircular in plan view and has radial anges 20 that are bent down to form pendent anges 21 for .itting over the post to 3*?)V designate clamp brackets that have elongated slots 8() for fitting over the ends of the bolts 8-8 on which they are held by the heads 8O of the said bolts and the nuts 81 that engage the threaded ends of said bolts. The body portion of each of the clamps is curved to lie atwise against the turned down flanges 21 of the cap plate 2.

9 designates a washer that lies under the plate 2 and over the upper edge of the band 1. W'asher 9 is formed of a yielding mn.- terial such for example, as heavy leather and its purpose is to act as a buffer and proteetiou for the plate'2 and the said upper edge of the banc 1.

From the foregoing description taken in connection with the drawing the complete construction, the manner in which my improvements are'used, together with the advantage thereof willv be readily understood.

The band 1 keeps the upper endof the post from excessive spreading, While* the plate 2 and the washer 9 serve to take up the impact or blow'of the Sledge and thereby acts to, prevent the post from splitting. The several parts are so connected that they can be readily used on posts of different. sizes, and when the plate 2 and washer 9 become worn, they can be easily replaced by a. plate and washer, all that is necessary to remove the old and substitute the new is to disconnect or loosen the bracket clamps 3 sufficiently to allow of lifting the worn plate and washer oft the top of the post.

What I- claim is:-

l. A post top protector comprising a cap portion to lit. over the post Iand spring clalnp devices connected therewith for gripping the side of the upper end of thepost.

'2. A driving cap for posts, comprising a band for surrounding the upper end of the post, a striking plate mounted on the band,

and means for clamping the band on the post, said means being removably connected to the post.

3. A striking means for fitting on the top of posts, comprising a band y for fitting around the post, a. striking member on the band, and means holding the band on the post and striking member clamped against the band.

4. A striking means for fitting on the top of posts, comprising a band of larger dialneter than the post, a striking member for rest.- ing on the. band and the top of the post, and means for clamping the post, said means being automatically adjustable for engaging posts 'of different diameters, said means being connected to and adapted for holding the balid and the striking plate in position on the post.

5. A. striking attachment for wooden posts consisting of the following elements in coinbination; an annular band having apertllred ears at opposite sides, alid pivot bolts mounted on the ends, iinrardly secured arms lillng from the said pivot bolts and having their lower ends projected below the band, a lveldinj.; striking plate mounted on the` top nti the band alid liaving a pelu lent portion lor straddliug the posty and devices carried by the band "for holding the striking plate ill position.

(l. striking :lttal-.liuieut for wooden posts consisting ot? the following elements ill conlbinaliou; an annular band having apertured ears at opposite, sides, and pivot bolts mounted n tlie ears` llwardl projecting arnls bling from tlie said pivot bolts and haring tlleil' lower ends projerled below the band. a` yielding Istriking plate mounted on the top of the band. tlie .striking plate having pendent llanges |`or sltraddling the upclamp devices being mounted on thet bination; an annular band having apertured f ears at opposite sides, and pivot bolts mounted in the ears, inwardly secured arms hungl from the said pivot bolts and having their lowcr ends projected below the band, ayielding striking plate mounted on the top of the band, the striking plate having pendent flanges for straddling the upper end of the band, and clamp devices for gripping the said flanges against the band, said clamp devices being removably lnolliited on the band.

S. A striking cap for posts comprising the following elements incombination; an annular band for fitting over the upper end of the post, a striking plate for resting on the said band and the post, clamping levers hung from the band and springs for closing said levers against the post.
